A wireless access control system for an electronic device comprises a personal locking device and an access control software module. The electronic device and personal locking device are Bluetooth-enabled and use Bluetooth to communicate with each other. The access control software is used to establish a Bluetooth link between these devices, based on the unique Bluetooth identifiers of the personal locking device and the electronic device. The personal locking device is preferably portable and is carried by the user at all times. Examples of preferred personal locking devices are cellular telephones, personal digital assistants, and pocket PCs. The Bluetooth radio chip and the Bluetooth communications protocol monitor the quality of service of the Bluetooth link between the devices. When the quality of service falls below a predetermined threshold, the access control software may switch the electronic device from an unlocked state to a locked state. When the quality of service rises above a predetermined threshold from below the threshold, the software may switch the electronic device from a locked state to an unlocked state.

A wireless, redundant, secure, real-time, network for a proprietary interactive data transfer system having a remote terminal and a host data center, such as an automated teller banking system, is disclosed. Controllers for the remote terminal and the host data center receive the proprietary language messages and packetize and encrypt the messages for sending over the best wireless carrier among the plurality of wireless carriers the controllers are connected to. The wireless control protocol monitors the communications to provide for selection of the most reliable communication carrier for any part of a transmission. Each network segment of the signal path has at least one state-controlled gate which reports the status of that signal path. Real time transmission and acknowledgment of securely packetized messages on wireless communications carriers via an object oriented coding control application provides for reliable datagram transfer independent of the reliability of any one signal path.

A protocol for differentiating congestion-related packet loss versus random packet loss in a wireless data connection. The protocol monitors changes in the length of a transmission queue in a wireless data connection over an interval substantially equal to the amount of time it takes to transmit a window of data packets and receive acknowledgements corresponding to all data packets transmitted in the window. If packet loss is preceded by an increase in the queue length over two consecutive intervals, the packet loss is designated as being due to congestion and a congestion avoidance algorithm is initiated. Otherwise, the packet loss is designated as random loss and the transmission window is maintained at its current size. The protocol reduces the transmission rate only when congestion is identified as the cause of lost packets; otherwise wireless losses can simply be quickly retransmitted without a reduction in the data transmission rate.

The present invention provides an improved transport protocol for lossy networks. This is accomplished by using computationally efficient techniques to manage invoking congestion control mechanisms to control the transmitted packets in lossy networks. The improved transport protocol receives multiple packets including a header and an associated sequence number.
